Im so sorry about your brother. I work on a cystic fibrosis ward, and have done for 8 years, so I've seen the heartache and horror watching relatively fit 20 year olds, turn in to shadows of themselves within 2 years. Ive always maintained I wouldn't wish it on my enemy.
And as fate has a twisted sense of fucked up humour, my daughter got diagnosed last year. So I fully know what horrors await my beautiful baby girl.
Life's a prick init?
